Product Description:
The MSK100C-0450-NN-S2-BG0-RNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. The unit converts electrical energy into controlled mechanical motion for positioning, feed, and handling tasks in industrial automation. It is intended for closed-loop servo systems in which the drive regulates current, speed, and shaft position during dynamic machine movement. Its compact housing is built for direct machine mounting, which helps the motor fit tightly integrated axis arrangements without requiring a separate protective enclosure.
Cooling for the motor is provided by natural convection, so heat leaves the housing without fans or liquid circuits. Position feedback uses the EnDat2.1 interface, allowing digital communication between the encoder and drive. The encoder supplies 2048 signal periods per revolution and relies on optical scanning for high angular resolution during controlled motion. Protection class IP65 seals the stator against dust and low-pressure water jets. The C-length frame in the size-100 package balances torque and inertia for responsive axis behavior, while increased rotor concentricity helps reduce radial runout. A power connector on the B-side supports orderly cable routing, and the motor is supplied without a holding brake for systems that use external stopping or clamping methods.
The mechanical output is through a plain shaft, so shrink-fit or clamp couplings can transmit torque without backlash from a keyed connection. Continuous use is permitted between 0–40 °C, which supports operation in standard indoor industrial conditions without derating. Insulation class 155 allows winding temperatures up to 155 °C during short peaks without degrading the winding varnish. Electromagnetic behavior is set by winding code 0450, matching the motor to compatible MSK drive modules. This combination of shaft style, thermal class, and winding selection supports accurate speed regulation and repeatable positioning in servo-controlled machinery.
